The demand for alcohol: The differential response to price
利用1983年美国全国健康访谈调查数据，研究不同饮酒量人群对酒精价格的反应差异，发现轻度和重度饮酒者的价格弹性远低于中度饮酒者，且最重度饮酒者的需求完全无弹性。
Although several studies indicate that drinking is responsive to price, little work has focused on whether prices have a differential effect on light, moderate, or heavy drinking. This study examines the price responsiveness of the demand for alcohol: whether heavy drinkers are less sensitive to price than light or moderate drinkers. The study uses data on alcohol consumption on the 1983 National Health Interview Survey. The results indicate that both light and heavy drinkers are much less price elastic than moderate drinkers. Further, we cannot reject the hypothesis that the very heaviest drinkers have perfectly price inelastic demands.
